' MARKER FOR CORN' ELANCERS.

it known that l, doi-iN H. Lone, a citizen of the United States, residing at Ashtabula, in the county of islatabiilzuy State oil Ohio, have invented cein new andnseitul` lmprovemcnts "in llaarkers tor. Corn Planters, oi which the` followingis afspecil iication.

corn planters, and an object of the invention is tol provide acorn planter` having devices for. marking places in they ground where seeds `have been dropped, irei'erence being had to Vthe accompanying drawings, in which Figure l is a sidefelevation, parts insection, otenough oit a corn planter to..illustrate .the application iolE the invention,

Figure i3 is a section. onthe line 2-2 o't Figure l, y y

Figure 3 is a vertical section on the line 3*3 otlligure l. Y

Figure 4 is a detail section taken substantially on the line lr-l of Figure 2 and illustrating the mechanism for. operating the seed dropping disc.

Figure 5 is a detail perspective view oi' one of the U-shaped brackets hereinafter re- :terred to.

Corn planters as commonly known generally employ a check rower wire which is stretched from one end of a iield to the other. This wire has lugs at intervals which are intended to operate the seed dropping mechanism when the corn planter is run along the wire. The stretching and moving of the wire consumes time, and its use -has otherdis advantages which become manifest upon consideration of the arrangement.

The improved corn planter has mechanism by which the seed dropping discs are operated automatically, and without the aid of any external device such as the wire spoken 'of above. The corn planter comprises a frame which is composed of a pair of transverse angle irons l. As these are the only members of the trame which have any bearingl on the invention the remainder ot the trame is omitted from the illustration.

Seed bones 2 and 3 are supported by the trame in any ordinary manner. 'ln this instance, these contain corn, rlhe seed boxes have short spouts l and 5 which terminate on top of seed discs 6 and 7. at places out of alignment with the conduits 8 and 9.

Each seed disc is perforated at 10 at a plurality of places,V and when'the seed .discs turn beneath'the spouts .4; and 5 seedsenter the perforations `and temporarily restion closure plates ll and .'12 untilmthe discs have turnednar enough to .bring the then 'lilled perforation into registration with. the

conduits. Thereupon the seed 'allslto Vthe y .ground and into a furrow opened by the j lily invention relates to improvements in L l discs 13 and 11i. .l Y

Each seed disc `is peripherally. toothed, at V15 and 16, so that it may be operated by dogs 17 and'l, respectively. 1 These dogs are pivotally .carried 19. by shortlupright arms 20 and. 2lk on a non-circular ransverse shaft n 22. i sleeves in `brackets 2li. the machineand` connectthe angle ironsgl mentioned'above. l i

It is to .be observed that thelrdogslt and 19 rest ontop'ofthe discs 6. .and 'l'. This rllhis i shaft carries `indicates that "they aref .held iniI place'f by gravity. Each dog is sul'liciently undercut at 5i (Fig. t) to provide suicient clearance tor the tooth next preceding when the disc is turned through the mediunio't the dog. ylhe extremity of each dog terminates in a heel which provides an ample rest for the dog on the teeth. f

The shai't 2Q is hereinafter known as ,thev checker shatt. lt carries marker arms and 26 and trip arms 27 and 28 at the respective extremities as clearly shown in Figures 2 and 3. Mounted in bearings 29 `onV brackets 30 and in a position above the seed boxes is a crank shaft 3l which has cranks 32 and 33 to periodically engage the trip arms Q7 and 28. rlhis is done simultane ously so that the turning nio-vement of the tion of earth andthus mark the place where 'seed has been dropped.

Springs i-O and il keep the marker Shanks in engagement with the fronts ot the slots E38 so that there may be no undue looseness ot the parts. Vlhese springs are connected between the Shanks and the Vfronts oi the brackets that guide them.

23 which furnish a bearing therefor These run; lengthwisefiot crank shaft 8l is continuous While the corn planter is in operation. The turning of the checker shaft 22, and consequently the Loperation of the dropping discs 6 and 7 is intermittent.

The operation may be readily;understood from the foregoing description. The corn Vplanter is drawn across the eld by means of draft animals hitched to the beam B according to the general custom. The' forward motion of the corn planter turns the crank shaft 31 and the `cranks 32 and 33 in the counter-clockwise direction (Fig. l). Each engagement of the trip ins Q7 and 28 by said cranks produces a turn of the checkery shaft 22. This resultsin the marker arms and 26 moving downward and the dog arms 20 and 21 rearward. I

The actions of turning the dropping discs 6 and 7 by means of the dogs 17 and 18, and

depressing` the spades 39 into the ground are simultaneous, or substantially so. As the machine proceedsforwardly the spades 39 Will dig out a portion of the earth and thus mark the places Where seeds are dropped. The slight turning of the dropping discs cause a certain one of each of the series of apertures 10 to move across the openings of the conduits 8 and 9 leading from the closure plates beneath so that seeds are releasedlVhile the construction and arrangement of the 'improved corn planter as herein described and claimed is that of a generally preferred form, obviously modifications and changes vmay be made without departing from the spirit of the invention or the scope of the claim.l

I claim:

In a planter, a checker shaft, a frame having U-shaped bracket supported beneath the frame, a slot in said bracket, an arm on the checker shaft, a shank carried thereby passing through said slot, a spade carried by said shank, and means including a spring holding the shank in engagei'nent with a portion of the slot, said spring having one end attached to one leg of said bracket and the opposite end to said shank.
